Ether and thioether amines and their use as fungicides

ABSTRACT

Amines of the general formula ##STR1## where A is alkyl, alkenyl, cycloalkyl, cycloalkenyl, phenylalkyl or phenylalkenyl, X is oxygen or sulfur, B is an alkylene chain and R 1  and R 2  are each alkyl, alkenyl or cycloalkyl, or R 1  and R 2  form part of a heterocyclic structrure, and their salts, as well as fungicides containing these compounds.

The present invention relates to novel amines, processes for their preparation, their use as fungicides, fungicides which contain the novel active ingredients, processes for the preparation of such fungicidal mixtures, and methods of combating harmful fungi with these fungicides.

It has been disclosed that N-tridecyl-2,6-dimethylmorpholine and its salts (eg. the acetate) can be used as a fungicide (DE Nos. 1 164 152 and 1 173 722).

We have found that compounds of the formula I ##STR2## where A is unsubstituted or substituted alkyl, alkenyl, cycloalkyl, cycloalkenyl, phenylalkyl or phenylalkenyl, X is oxygen or sulfur, B is an alkylene chain of 2 to 10 carbon atoms which is unsubstituted or monosubstituted or polysubstituted by alkyl of 1 to 4 carbon atoms, and R¹ and R² are identical or different and independently of one another are each C₁ -C₁₀ -alkyl, C₃ -C₆ -alkenyl or C₃ -C₈ -cycloalkyl, or R¹ and R² as an alkylene group form part of a 5-membered, 6-membered or 7-membered heterocyclic structure which contains from 1 to 3 heteroatoms (nitrogen, oxygen or sulfur), does not possess a double bond in the ring and is unsubstituted or substituted by one or more, eg. 1 to 3, alkyl groups, each of which is of 1 to 4 carbon atoms, and their salts are very effective against harmful fungi and are very well tolerated by plants.

The novel amines of the formula I may contain chiral centers. They are generally obtained as racemates and may be obtained as diastereomer mixtures. In the case of some of the novel compounds, pure diastereomers can be isolated in pure form, for example by column chromatography or by virtue of solubility differences. Pure racemates and enantiomers can be obtained from such purified diastereomers by a conventional method. All these compounds and mixtures are embraced by the present invention. Regarding the use of the novel amines, the pure diastereomers and enantiomers as well as the mixtures of these obtained in the synthesis are suitable for use as fungicides. The said mixtures are preferably used.

Advantageously, the solvent is used in an amount of from 100 to 2,000, preferably from 200 to 700, % by weight, based on starting material II.

All conventional acid acceptors can be used as inorganic or organic bases for the conversion to compounds of the formula I.

Examples are chlorides, bromides, iodides, sulfates, phosphates, acetates, oxalates, fumarates, malonates, alkylsulfonates and arylsulfonates.

The salts are obtained by combining the appropriate acid with the free amine of the formula I in the presence or absence of an inert solvent, separating off the solvent and, if required, recrystallizing the residue.

EXAMPLE 1

A stirred mixture of 41.1 g (0.15 mole) of 4-(cyclododecyloxy)-1-chlorobutane, 120 ml of cis-2,6-dimethylmorpholine and 3 g of potassium iodide was heated at 90° C. for 24 hours. The reaction mixture was cooled to 10° C., after which 100 ml of petroleum ether and 70 ml of 20% strength aqueous sodium hydroxide solution were added in succession. The organic phase was washed with three times 80 ml of water, dried over Na₂ SO₄ and subjected to fractional distillation under reduced pressure.

46.8 g (88.4% of theory) of N-(cyclododecyloxybutyl)-cis-2,6-dimethylmorpholine were obtained as a colorless oil of boiling point 181°-182° C./0.15 mbar and n_(D) ²² =1.4832.

EXAMPLE 2

A thoroughly stirred mixture of 42 g (0.12 mol) of N-(3-hydroxy-2-methylprop-1-yl)-2,6-dimethylmorpholine, 100 ml of 2-ethylhexyl chloride, 4 g of tetrabutylammonium chloride and 70 g of 50% strength aqueous sodium hydroxide solution was heated at 50° C. for 72 hours. Thereafter, 200 ml of water were added to the mixture, which was then extracted with three times 100 ml of methylene chloride. The combined extracts were washed with five times 80 ml of water, dried over sodium sulfate and fractionated under reduced pressure.

6.2 g (17.3% of theory) of N-[3-(2-ethylhexyloxy)-2-methylprop-1-yl]-2,6-dimethylmorpholine were obtained as a colorless oil of boiling point 130° C./0.1 mbar and n_(D) ²² =1.4504.

EXAMPLE 3

66.5 g (0.46 mole) of 3,5,5-trimethylhexanol, 19 g (0.092 mole) of N-(3-chloro-2-methylprop-1-yl)-2,6-dimethylmorpholine, 2 g of tetrabutylammonium bisulfate and 65 g of 50% strength aqueous sodium hydroxide solution were reacted at 50° C. for 72 hours by a procedure similar to that described in Example 2.

15 g (52.1% of theory) of N-[3-(3,5,5-trimethylhexyloxy)-2-methylprop-1-yl)-2,6-dimethylmorpholine were obtained as a colorless liquid of boiling point 135° C./0.2 mbar and n_(D) ²² =1.4486.

EXAMPLE 4

20.2 g (0.1 mole) of n-dodecylmercaptan were added dropwise to a stirred suspension of 3.2 g (0.13 mole) of sodium hydride in 120 ml of dry dimethylformamide at from 20° to 25° C. in a dry nitrogen atmosphere. The mixture was stirred for two hours at 20° C., after which 19.2 g (0.1 mole) of N-(3-chloroprop-1-yl)-2,6-dimethylmorpholine were added dropwise and the reaction mixture was stirred for a further 16 hours. 40 ml of ice water were carefully added dropwise, and the mixture was evaporated down under reduced pressure. The residue was partitioned between 300 ml of ether and 80 ml of water, and the organic phase was washed with twice 100 ml of water, dried over Na₂ SO₄ and evaporated down. The residue was distilled under reduced pressure.

29.5 g (82.6% of theory) of N-[3-(n-dodecylthio)prop-1-yl]-2,6-dimethylmorpholine were obtained as a colorless oil of boiling point 175°-176° C./0.05 mbar and n_(D) ²² =1.4772.

In general terms, the novel compounds are very effective against a broad spectrum of phytopathogenic fungi, in particular those from the class consisting of the Ascomycetes and Basidiomycetes. Some of them have a systemic action and can be used as foliar and soil fungicides.

The fungicidal compounds are of particular interest for controlling a large number of fungi on various crops or their seeds, in particular wheat, rye, barley, oats, rice, corn, cotton, soybean, coffee, sugar cane, fruit and ornamentals in horticulture, in viticulture, and for vegetables, such as cucumbers, beans and Cucurbitaceae.

The novel compounds are particularly useful for controlling the following plant diseases:

Erysiphe graminis in cereals,

Erysiphe cichoracearum and Sphaerotheca fuliginea in Cucurbitaceae,

Podosphaera leucotricha in apples,

Uncinula necator in vines,

Puccinia species in cereals,

Rhizoctonia solani in cotton,

Ustilago species in cereals and sugar cane,

Venturia inaequal is (scab) in apples,

Septoria nodorum in wheat,

Pyrenophora teres in barley,

Botrytis cinerea (gray mold) in strawberries and vines,

Cercospora musae in bananas,

Pseudocercosporella herpotrichoides in wheat and barley,

Pyricularia oryzae in rice,

Hemileia vastatrix in coffee,

Alternaria solani in potatoes and tomatoes,

Plasmopara viticola in vines, and

Fusarium and Verticillium species in various plants.

The compounds are applied by spraying or dusting plants with the active ingredients, or treating the seeds of the plants with the active ingredients. They are applied before or after infection of the plants or seeds with the fungi.

The novel substances can be converted to the conventional formulations, such as solutions, emulsions, suspensions, dusts, powders, pastes and granules. The forms for use depend entirely on the purposes for which they are intended; they should at all events ensure a fine and uniform distribution of the active substance. The formulations are produced in a known manner, for example by extending the active ingredient with solvents and/or carriers, with or without the use of emulsifiers and dispersants; if water is used as a diluent, it is also possible to employ other, organic solvents as auxiliary solvents. Suitable assistants for this purpose are essentially solvents, such as aromatics (eg. xylene or benzene), chlorinated aromatics (eg. chlorobenzenes), paraffins (eg. oil fractions), alcohols (eg. methanol or butanol), ketones (eg. cyclohexanone), amines (eg. ethanolamine or dimethylformamide) and water; carriers, such as ground natural minerals (kaolins, aluminas, talc or chalk) and ground synthetic minerals (eg. highly disperse silica or silicates); emulsifiers, such as nonionic and anionic emulsifiers (eg. polyoxyethylene fatty alcohol ethers, alkylsulfonates and arylsulfonates) and dispersants, such as lignin, sulfite waste liquors and methylcellulose.

The fungicides generally contain from 0.1 to 95, preferably from 0.5 to 90, % by weight of active ingredient.

The application rates are from 0.02 to 3 kg or more of active ingredient per ha, depending on the type of effect desired. The novel compounds may also be employed in material protection, inter alia for controlling wood-destroying fungi, such as Coniophora puteana and Polystictus versicolor. The novel active ingredients can also be used as fungicidal components of oily wood preservatives for protecting wood against wood-discoloring fungi. They are used by treating, for example impregnating or painting, the wood with these agents.

The agents and the ready-to-use formulations prepared from them, such as solutions, emulsions, suspensions, powders, dusts, pastes or granules, are applied in a conventional manner, for example by spraying, misting, dusting, scattering, dressing or watering.

Examples of such formulations are:

I. 90 parts by weight of compound No. 3 are mixed with 10 parts by weight of N-methyl-alpha-pyrrolidone to give a solution which is suitable for application in the form of very small drops.

II. 20 parts by weight of compound No. 23 are dissolved in a mixture which consists of 80 parts by weight of xylene, 10 parts by weight of the adduct of from 8 to 10 moles of ethylene oxide with 1 mole of oleic acid N-monoethanolamide, 5 parts by weight of calcium dodecylbenzenesulfonate and 5 parts by weight of the adduct of 40 moles of ethylene oxide with 1 mole of castor oil. By pouring the solution into water and dispersing it finely, an aqueous dispersion is obtained.

III. 20 parts by weight of compound No. 24 are dissolved in a mixture which consists of 40 parts by weight of cyclohexanone, 30 parts by weight of isobutanol and 20 parts by weight of the adduct of 40 moles of ethylene oxide with 1 mole of castor oil. By pouring the solution into water and dispersing it finely, an aqueous dispersion is obtained.

IV. 20 parts by weight of compound No. 26 are dissolved in a mixture which consists of 25 parts by weight of cyclohexanol, 65 parts by weight of a mineral oil fraction having a boiling point of from 210° to 280° C. and 10 parts by weight of the adduct of 40 moles of ethylene oxide with 1 mole of castor oil. By pouring the solution into water and dispersing it finely, an aqueous dispersion is obtained.

V. 80 parts by weight of compound No. 27 are mixed thoroughly with 3 parts by weight of sodium diisobutylnaphthalene-alpha-sulfonate, 10 parts by weight of the sodium salt of a ligninsulfonic acid obtained from a sulfite waste liquor, and 7 parts by weight of powdered silica gel, and the mixture is milled in a hammer mill. By finely dispersing the mixture in water, a spray liquor is obtained.

VI. 3 parts by weight of compound No. 42 are mixed intimately with 97 parts by weight of finely divided kaolin to give a dusting agent which contains 3% by weight of the active ingredient.

VII. 30 parts by weight of compound No. 57 are mixed intimately with a mixture of 92 parts by weight of powdered silica gel and 8 parts by weight of paraffin oil, which has been sprayed onto the surface of this silica gel. This gives a formulation of the active ingredient which possesses good adhesive power.

VIII. 40 parts by weight of compound No. 59 are mixed thoroughly with 10 parts of the sodium salt of a phenolsulfonic acid/urea/formaldehyde condensate, 2 parts of silica gel and 48 parts of water to give a stable aqueous dispersion. By dilution with water, an aqueous dispersion is obtained.

IX. 20 parts of compound No. 74 are mixed thoroughly with 2 parts of calcium dodecylbenzenesulfonate, 8 parts of a fatty alcohol polyglycol ether, 2 parts of the sodium salt of a phenolsulfonic acid/urea/formaldehyde condensate and 68 parts of a paraffinic mineral oil. A stable oily dispersion is obtained.

In these application forms, the agents according to the invention may also be present together with other active ingredients, for example herbicides, insecticides, growth regulators and fungicides, or may furthermore be mixed with fertilizers and applied together with these. Mixing with fungicides frequently results in a greater fungicidal action spectrum.
